More thoughts on the Caltrain stats in the last post...
Here is exactly why the shuttle ridership is dropping more than the
In the past year Apple and Genentech - companies that both have large
shuttle programs taking
employees from Caltrain to the office, introduced shuttles that take
employees directly from San
Francisco to the office. People who used to take Caltrain to Mountain
View or SSF to get a company
shuttle, now aren't on the Caltrain at all.
Now, of course this drops Caltrain ridership by N as well as Caltrain
Shuttle ridership by N. However, the
PERCENTAGE impact to the shuttle ridership numbers is substantially
I picked Oct 2008 out of a hat. 41,893 riders daily. 6316 Shuttle
riders - the stats don't indicate if that is
daily or monthly. My guess - that's monthly ... e.g. 210 riders on
shuttles per day. If 10 people switch from Caltrain-Shuttle
to Company Shuttle, that lowers the Caltrain ridership by 20/41893 =
which is close to zero. Those same 20 rides
(remember this is round trip) lower the shuttle ridership by 10
Caltrain may only be counting shuttles that they are affilliated with
(listed on Caltrain website) so Apple may not be included.
I can't verify all my math or my facts, but this has to be a nominal factor.
